Our site can be visited without active information about the user. However, we automatically save access data (server log files), such as the name of the Internet service provider, the operating system used, the website from which the user visits us, the date and duration of the visit, the name of the requested file and the IP address of the device used. We store this information for a period of 7 days for security reasons, e.g. to detect attacks on our website. This data is not consolidated with other data sources.
